All nonsense, I buy a cheap wall printer from China and save a lot of money!

You get what you pay for. And when you buy cheap, you usually buy twice.

Why do we say that?

You should think carefully and decide for yourself whether you want to run a professional business with professional equipment and support in the long run, or whether you want to surround yourself with questionable Far Eastern technology that you can get cheaply but that certainly doesn't match your understanding of quality and sustainability.

If you want to work professionally, you should also reach for professional tools.

So please ask yourself:

What if something doesn't work as expected?
What if spare parts are missing later?
What if there are suddenly no more updates for the Chinese software?
What if you really need urgent help?
What if the printing results are not as expected?
What if a competitor suddenly owns a wallPen and steals your thunder?
What if your customer won't accept Far Eastern solvent-based ink in their building?
Most customers with such machines find out the hard way why the equipment was so incredibly cheap and why their business is now in grave danger. They have only then wasted a lot of time and money hoping to save a few euros or dollars per hour of operation.

They should keep in mind that most printers also spend a lot of money on their flatbed presses, even though such equipment is also available in China for a fraction of the price. Why don't these companies save money? Because they think economically and in the long term and don't just look at the low purchase price. Quality has its price.

What does wallPen GmbH have to do with the "Chinese Wallpen"?

Nothing! This company has just unfortunately stolen many of our ideas and concepts, basically trying to copy our machine and even illegally using our trademarked brand name "wallPen" against our will. The company makes itself liable to prosecution in many respects and we can only warn very strongly against buying such cheap copies - both directly and via their partner network.

The danger for customers: The device cannot be legally operated because it clearly infringes our patent rights.

Is the purchase of a wallPen® subsidized by the state?

Most likely yes. In many countries, the government provides very intensive support for new and innovative technologies such as the wallPen. However, the nature and availability of funding programs varies widely among countries around the world. Many regions in the European Union, for example, offer innovative technology funding with grants ranging from 20% to 100%!

Technical questions

Is a special power connection required?

The wallPen® runs on standard household AC voltage between 100 and 250V. The power consumption is only in operation about 200 watts maximum - less than a conventional hair dryer. The power consumption in idle mode is less than 40 watts.

Are there multiple models or designs?

No, the wallPen® is what it is: a proven and flexible solution to print perfectly on vertical surfaces. What we do offer, however, are some options to meet special project requirements. This makes our solution all the more future-proof for our customers and also expandable at any time.

Do you have a manual?

Yes, along with the machine comes a printed and very detailed English manual (200+ pages) along with the German translation in PDF format.

Is there a steering system?

Yes, it is motor-driven and integrated into the front axle.

What hardware is used?

The wallPen® E2 operates on a 32-bit ARM multiprocessor system with a specially developed UNIX operating system.

How much does the wallPen® weigh?

The total weight is 90 kg, divided into 6 portable bags. The heaviest bag weighs 25 kg and can be easily carried and stored

Questions about the printing process

How does the wallPen® works?

Vertical printing uses four separate drop-on-demand (DOD) inkjet printheads with CMYK colors (cyan, magenta, yellow, black). The unit automatically moves along the wall on a steered, patented platform on wheels controlled by laser sensors. Rails are not required, but are optionally available for cases where the floor is not sufficiently level.

What is the print resolution?

The wallPen supports print resolutions between 300 to 1200 DPI.

As a rule, most images are rasterized and printed in 600 x 720 DPI. Don't be fooled by the fantasy numbers of the competitors. Real (!) 600 DPI on the wall is already absolutely stunning in real terms, especially since wall prints are usually large motifs and are always viewed from some distance.

Which ink is used?

Specially formulated, plastic-like, low-odor wallPen UV ink from European production. The ink is supplied in 200ml bottles and refilling can be done easily and quickly at any time - even during a printing break - using the syringes supplied.

Does the ink run out?

UV ink can be stored for at least 12 months after delivery.

How many square meters can be printed with one set of CMYK ink?

Since the ink can be quickly and cleanly refilled at any time, there is virtually no limit to the amount of ink you can use. As for the price, experience shows that the cost of the ink varies somewhere between 2 and 6 euros per square meter.

Can the inks be replaced individually per color or with a different ink?

If required, the ink is simply sucked out of the bottle of the desired color with a syringe and refilled into the tank cleanly and drip-free via a connector. In this way - unlike most other systems - hardly any ink is wasted!

We strongly recommend to use only wallPen ink. The use of any other ink will void any warranty.

Is the print result later also UV-resistant, scratch-proof and durable?

We guarantee that our ink will retain its color for at least 12 years indoors. Outdoors, the UV resistance is 2 years unprotected, but can be extended to more than 5 years by applying a transparent UV coating.

In general, the ink is immediately dry and scratch resistant immediately after printing.

Which software is used?

The printer is operated via the wallPen web app. Our in-house developed RIP software, the "wallPen Processor" is installed on an external PC or laptop (Windows and MacOS) to process images into .wallpen file and thus prepare them for printing.

Both programs are included in the delivery.

How is the wallPen® used?

The device is operated securely and conveniently via an internal WLAN network and the supplied tablet, but can also be operated with any other mobile device (smartphone, laptop).

Repair and service

Where can I find support if I have problems?

If you have questions about or problems with your wallPen, please contact your wallPen partner or wallPen Germany directly. However, many technical questions are already answered in the manual and FAQ section of the helpdesk at As a wallPen customer, you get full access here free of charge.

How much does the support cost?

The price of the wallPen includes warranty, telephone hotline and all software updates for one year. During this time you are fully covered in case of questions or problems. For the time after that, we offer you an optional maintenance contract. This costs 0.5% of the purchase price per month and can be concluded for up to three additional years. Customers without a maintenance contract will be invoiced for the costs incurred after the warranty period and settled fairly.

Is there a guarantee?

The wallPen® includes one year full warranty, hotline, support, service and software updates. An optional service and support upgrade to a total of up to four years is available upon request.

Is there an insurance for the device?

Countries and regulations are too different to offer a general insurance. It is best to ask your local insurance partner whether they can offer you insurance for the wallPen, e.g. for theft, liability, vandalism or even negligence.

How long do the printheads last?

The service life depends largely on handling, maintenance and care. With appropriate care, a head can even last for years.

Should one fail, however, this is not the end of the world. This can be replaced separately, as we do not use "combination heads" as our Chinese competitors do. There is a separate print head for each color.

How can I order spare parts?

You can order any spare part or accessory either from your local dealer or directly from us. Most spare parts are shipped from stock. Accessories (such as custom axle extensions) can take up to 30 business days.
